BALL-BEARNG I'CUSING.

Application filed May 13, 1927. Serial No. 151,111

The object of my invention is to provide va housing for a ball-bearing which can be adjusted W vertically or laterally without cramping er binding the vorlrlng parts of the ball-bearing. rlhe bindingof the parts in many instances ruin the ball-bearing.

' ln the accompanying d 1a 'ingr l is a sectional view on the line 1 1, 2, showing the ball-bearing housing in 7ation;

lig. 2 is a sectional view on the line 2 2, ig. l, also showing the housing in elevation; and

Fig. 3 is a plan view.

rlhe trame l, in the present instance, is shaped to lit the structural supports ot a drying machine, and the shaft 2 is fan shaft extending into the drier and provided with a :tan at its inner end and a driving pulley at its outer end, but it will le underq stood that the traine can be ot any shape, depending upon the. machine or apparatus to which it is attached.

The housing `8 for the ball-bearing l is shaped, in the present instance, as shown in Figs. l and 2, and has laterally extending lugs 5 5 shaped to receive the ends of the adjusting screws.

The two screws 6 6 are arranged horizontally and bear upon the ends et the lugs, and by adj Listing the screws 5 6, the housing be moved laterally.

The screws 6 6 extend through vertical slots 7 7 in the frame l, and on the screws at each side ot' the slotted portion oi the frame are nuts S and 9, for locking the screws in the position in which they are adjusted. The slots 7 allow the housing to be adjusted vertically by other screws.

ln order to adjust the housing vertically, tour screws lO-lO are provided. The screws l0 bear upon the upper surface of the lugs 5 5,V and extend through slots 1l in the trame l. On each screw are nuts l2 and 13 which clamp the screws rinly to the l'rame after adjustment.

rl`he screws l() extend through slots 1la in the traine and bear upon the underside of each of the lugs 5. On the screws l02L are nuts 12"L and 13a which conne the screws to the frame after adjustment.

By the above-described construction, the ball-bearing housing can be shifted as described to bring the shaft in proper `alignment with the rest et the equipment.

The lugs 5 are made substantial so that any pressure exerted upon the lugs will not disturb the body ot the housing and the ball-bearing.

ln sonic instances, the lugs 5 may be slotted, at ll, in alignment with the side bearing screws 6 6, so that when excessive pressure is applied by turning said screws, the cast metal between the slot and the end oitl the screw would give and thereby prevent possible distortion of the housing and bearing.

Yfhen it is wished to adjust the housing laterally, the screws 1(3 10a are released from the traine by turning the nuts. Then the screws 6 6 can be turned to shitt the housing to the position desired, and after adjustment the several nuts can be tightcned,

lf the housing` is to be adjusted vertically, then the nuts on the screws 6 6 are backedcti and the screws l() l0L turned. When the housing has been moved to the position desired, then the nuts are tightened.

I claim:

l. The combination of a frame; a housing mounted in the traine; laterally extending lugs on the housing; adjusting screws bearing against the end of each lug; vertically adjustable screws bearing upon the upper and lower sides or" the lugs, the trame being slotted for the passage of the several screws and nuts on each; and screws on each side of the slotted portions of the traine for holding the screws after adjustment.

2. rfhe combination ot' a. iframe; a housing located in the frame, said housing having a lug at each side; means for vertically adjusting the housing; and adjusting screws bearing against the ends of the lugs, said lugs being slotted in line with the screws to allow the metal between the slots and the ends of the screws to give under excessive pressure.
